The Commons committee welcomed the commitment by the Internet Watch Foundation to embark on proactive searching for abuse, but warned there were "concerns" about current levels of funding and capacity.

Concerned that seven additional staff might prove woefully insufficient to achieve substantial progress towards what must be an important intermediate goal: the eradication of child abuse images from the open internet.

It said there was:

A clear need to ensure that the police have adequate resources to track down and arrest online paedophiles in sufficient numbers to act as a meaningful deterrent to others.

If necessary, additional funding should be provided to recruit and train a sufficiently large number of police officers adequate to the task.

Tory MP John Whittingdale has called on internet companies to do more to protect children from viewing images of child abuse and porn online.

In a warning that current efforts to eradicate images of child abuse may prove "woefully inadequate" he said:

We do not think there needs to be more regulation, and certainly not to stifle all the positive purposes and uses of the internet, but those who profit from the internet must demonstrate the utmost commitment to protecting children and should be prosecuted and penalised if they don't.

Facebook and Twitter, for example, are aware of the extent to which their services are accessed by younger children, thanks to age verification processes that are at best flimsy.

We expect them to pay greater attention to factoring this into the services provided, the content allowed and the access to both.

The same applies to other social media companies in a similar position. Bullying that takes place in the playground can merge seamlessly with bullying on smart phones and tablets.
